Temporal bone findings in keratitis, ichthyosis, and deafness syndrome. Case report

In 1981, the term KID syndrome was suggested for patients with congenital ichthyosis associated with deafness and keratitis. We had a chance to examine the temporal bone of an infant with this syndrome. This patient showed no auditory brain stem response in either ear. Temporal bone studies revealed cochleosaccular abnormality. These findings are offered as a possible explanation for the patient's deafness. The pathologic inner ear findings of congenital deafness syndromes associated with ichthyosis have been heretofore reported in Refsum's syndrome and in a case with universal alopecia. In these cases, the temporal bone pathologic findings were a result of cochleosaccular abnormality. From our case and previous reports, it is suggested that the deafness associated with congenital ichthyosis might be the result of cochleosaccular abnormality.
